简易避雨棚栽培对赞皇大枣裂果及品质的影响研究

The Effect of Simple Rain Shelter Cultivation on Fruit Rot Rate and Quality of Zanhuang Jujube

赞皇大枣白熟期遇阴雨天会开裂腐烂,露地栽培赞皇大枣一般年份裂果浆烂率达35%左右,成熟期遇多雨年份,裂果浆烂率高达50%~80%,给枣农造成重大损失,严重挫伤枣农的积极性。本试验针对简易避雨棚栽培和露地栽培对赞皇大枣的裂果和品质影响进行了试验,结果表明,采用简易避雨棚栽培比露地栽培的枣裂果浆烂率明显降低,平均单果重、氨基酸、蛋白质、VC、可溶性总糖含量增加,提高了赞皇大枣的品质,枣的售价提高,经济效益也得到了提高。

The fruit rot rate of Zanhuang jujube,which are planted in open area,is about35%in average year.The fruit rotrate is as high as50%~80%,if it encounter a rainy year maturity,which could cause major losses to the farmers,andcombat the enthusiasm of farmers.The effect of simple rain shelter cultivation and open field cultivation on cracking rateand quality of Zanhuang jujube were analysed.The results showed that the fruit cracking rate of the simple shelter sheddecreased significantly comparied with open field cultivation,the average fruit weight increased,the contents of aminoacids,proteins,VC and total soluble sugar increased,and its'quality of Zanhuang jujube was raised,the price of jujubewas raised,and the economic benefit was improved.
